Abstract

The present invention provides a wound dressing comprising (i) an absorbent layer portion capable of absorbing wound exudates and arranged to receive wound exudates in use, the absorbent layer portion comprising a hydrogel; and (ii) a backing layer which overlies the absorbent layer portion to a side, which, in use, is directed away from the wound, and wherein the backing layer has a moisture vapour transmission rate (MVTR) of from about 300 to about 1100 g/m2/24hours.
